My engine knowledge ends at stage 3......what can you tell me about stage 4????? Who does the mods????? How much for the engine?????? What additional upgrades are required?????? Does the car need to be shipped to an installer????? Is reliability an issue? (My wife is no longer allowed to drive my stuff)
I would appreciate answers to any of these questions.....
Thanks
Here is the part list from the VW Vortex Super Beetle page (essentially its a GolfR drivetrain swapped into a Beetle)
- APR Stage IV GTX Turbocharger System
- APR Boost Tap
- APR High Pressure Fuel Pump
- APR Low Pressure Fueling System
- APR Rail Pressure Release Valve
- APR Intercooler System
- APR Stage IV ECU Upgrade with ESP Delete
- APR Stage IV High Flow Head
- APR Stage IV High Flow Intake Manifold RF Delete
- APR Stage IV Low Pressure Fueling System
- APR Stage IV High Strength Coated Pistons & Wrist Pins
- APR Stage IV High Strength Connecting Rods & Bearings
- APR Stage IV Balanced Rotating Assembly
- APR RSC Turboback Exhaust System
- DXD Racing Stage III Clutch
- Volkswagen Racing Short Shifter
Essentially the majority of this stuff are things you are gonna need to replace on your motor because of the money shift...
If you want to go the cheap route just replace the head and valves as long as the pistons are ok... but since the engine is gonna be apart might as well go all in (that's essentially what I did when I screwed my engine from overheating... no it's ready for an APR Stage 3+ system)

As long as you know a good local installer should be fine. Lucky for me I have a good local shop out here in Socal that did my engine build 25,000 miles ago with many hard track days and the engine is running strong as ever. As long as everything is done right it will be reliable. My engine builder gave me a 2 year 10,000 mile warranty on their work. The good thing is that If I wanted to got stage 3+ on my car I know my engine can take it
If you don't know anyone local that is reliable, then just have APR do all the work to take out all the guess work just like in VW Vortex's SuperBeetle project. OTOH if you know a local VW/ Audi shop that wants to get their name out I bet you can work out a sponsorship with that shop on the labor since this will be one of 3 VW Golf R's (yours, APR's Golf R, and the VW Vortex SuperBeetle) in the country with a stage 4 setup.
